Timming gear problems in a 350 four bolt main


#1

I have a 1981 monte carlo. I have dropped a 350 4 bolt main into it. I replaced the timming chain for gears. I thought it was the gears rubbing the timming cover and when i pulled the cover off I found that they were. I fixed the problem of the gears rubbing by beating the cover off a little and adding 2 extra gaskets to space it away from the gears. When I start the car and let it idle it doen’t make a noise, but when I rev it up it sounds like it is rubbing somewhere. Could it be the hormonic balancer or have you heard of any problem like this and know how I can fix it?

Are you sure it is not the typical annoying noise made by gear drive engines?


#3

What is the exact manufacturer and part number of the gear set you installed?

Are you running a cam button to limit cam walk?

Sometimes you have to get a cover that is designed for what you install.
